FamilySymbol Location?

Revit

Hi,
I accessed the slope and span of family symbols.
How do I access each Location Point and Rotation?

import clr
clr.AddReference("RevitServices")
from RevitServices.Persistence import DocumentManager
clr.AddReference("RevitAPI")
from Autodesk.Revit.DB import *

doc = DocumentManager.Instance.CurrentDBDocument
categories = doc.Settings.Categories

all_elements = []

for category in categories:
    collector = FilteredElementCollector(doc).OfCategoryId(category.Id)
    elements = collector.ToElements()
    if(len(elements) > 0):
        all_elements.extend(elements)
tset = []
tset.append(["Id","type","slope","span","x","y","z","angle"])

for e in all_elements:
    pslope = 0
    pspan = 0
    pref = ""
    pskip = 1
    pnset = []
    for p in e.Parameters:
        if("SLOPE" in p.Definition.Name.upper()):
            pslope = p.AsDouble()
        if("SPAN" in p.Definition.Name.upper()):
            pspan = p.AsDouble()
        #
        if(p.AsString()is None):
            continue
        param_group = p.Definition.ParameterGroup
        param_group_name = LabelUtils.GetLabelFor(param_group).upper()
        if(param_group_name != "IFC PARAMETERS"):
            continue
        pnset.append(p.Definition.Name)
        if(param_group_name == "IFC PARAMETERS" and p.Definition.Name == "Reference"):
            if p.AsString() == "":
                pskip = 1
                continue
            pref = p.AsString()
            pskip = 0
    if pskip == 0:
        loc = e.Location
        lp = None
        lpx = None
        lpy = None
        lpz = None
        lr = None
        if isinstance(loc, LocationPoint):
            lp = loc.Point
            lpx = lp.X
            lpy = lp.Y
            lpz = lp.Z
            lr = loc.Rotation
        elif isinstance(loc, LocationCurve):
            lp = loc.Curve.Evaluate(0.5, True)
            curve = loc.Curve
            direction = curve.GetEndPoint(1) - curve.GetEndPoint(0)
            lr = direction.AngleTo(XYZ(1, 0, 0))        
        tset.append([e.Id, type(e) , pref, pslope, pspan,lpx,lpy,lpz,lr])
           

OUT = tset

Thx for your patience,
K.

Hi,

Revit imports IFC elements as in-place elements, they have no Location attribute like native Revit elements.

You can try re-constructing this location with the Line.ByBestFitThroughPoints() method for Line Based Elements (with vertices)
